Reference is made to FIGS. 1-2 . FIG. 1 is a schematic view of a coldplate module 100 according to an embodiment of the present disclosure.FIG. 2 is an exploded view of the cold plate module 100 of FIG. 1 . Inthis embodiment, as shown in FIGS. 1-2 , a cold plate module 100includes a cold plate 110 (please see FIG. 2 ), a structural piece 120and a plurality of first connecting pieces 130. The cold plate 110 isconfigured to abut against a heat source 200 (please see FIG. 2 ) inorder to carry out heat dissipation to the heat source 200 bytransferring the heat energy of the heat source 200 away. For example,the heat source 200 can be a chip or a die, which is disposed on a mainboard 300 of an electronic device. For example, the main board 300 canbe an application specific integrated circuit (ASIC) board. However,this does not intend to limit the present disclosure. The structuralpiece 120 is configured to abut against and connect with the cold plate110. The first connecting pieces 130 penetrate through the structuralpiece 120 and connect with the main board 300, so as to firmly fix thestructural piece 120 together with the cold plate 110 on the heat source200. It is worth to note that, in this embodiment, the cold plate 110 islocated between the structural piece 120 and the heat source 200, whilethe structural piece 120 and the cold plate 110 are detachable from eachother.

Reference is made to FIG. 3 . FIG. 3 is a schematic bottom view of thestructural piece 120 of FIG. 1 . In this embodiment, as shown in FIGS.1-3 , the structural piece 120 includes a plate body 122, a plurality ofconnecting portions 123 and a plurality of bending portions 125. Thestructural piece 120 has a third surface 121. The third surface 121 islocated on the plate body 122 and is configured to abut against the coldplate 110. Each of the connecting portions 123 has a fourth surface 124.The fourth surfaces 124 are configured to face to the main board 300.The first connecting pieces 130 are configured to penetrate through theconnecting portions 123 of the structural piece 120 and connect with themain board 300, so as to firmly fix the structural piece 120 togetherwith the cold plate 110 on the heat source 200. The bending portions 125are respectively connected between the plate body 122 and thecorresponding connecting portion 123. The plate body 122 is connectedbetween the bending portions 125.

In practical applications, the plate body 122, the connecting portions123 and the bending portions 125 are an integrally formed structure.Thus, the structural piece 120 has a better structural strength.

In this embodiment, as shown in FIGS. 1-3 , the quantities of thebending portions 125 and the connecting portions 123 of the structuralpiece 120 are both two. The bending portions 125 and the connectingportions 123 are both located on two opposite sides of the plate body122. In other words, the bending portions 125 are separated from eachother, and the connecting portions 123 are also separated from eachother.

Reference is made to FIG. 4 . FIG. 4 is a cross-sectional view along thesectional line A-A of FIG. 1 . In this embodiment, as shown in FIG. 4 ,the cold plate 110 has a first surface 111 and a second surface 112opposite to the first surface 111. The first surface 111 of the coldplate 110 is configured to abut against the heat source 200 disposed onthe main board 300. The third surface 121 of the structural piece 120 isconfigured to abut against the second surface 112 of the cold plate 110.Thus, the cold plate 110 is located between the structural piece 120 andthe heat source 200. The fourth surfaces 124 of the connecting portions123 and the main board 300 have a gap G therebetween. Thus, the coldplate 110 can be tightly clamped between the structural piece 120 andthe heat source 200. It is worth to note that, as the bending portions125 are connected between the plate body 122 and the connecting portions123, the fourth surfaces 124 of the connecting portions 123 and thethird surface 121 of the structural piece 120 have a height differenceHD. In other words, the fourth surfaces 124 of the connecting portions123 and the third surface 121 of the structural piece 120 are notlocated on the same height level. In this way, the structural piece 120has a reinforced moment of inertia. This means the structural piece 120has a good structural strength and is uneasy to be deformed.

Since the structural piece 120 has a good structural strength, when thecold plate module 100 or the main board 300 experiences an impact or avibration, the structural piece 120 is uneasy to be deformed and thestructural piece 120 can maintain its original shape. In this way, dueto the structural strength of the structural piece 120, the cold plate110 abutting against the third surface 121 of the structural piece 120will not be deformed under an impact or a vibration. Thus, the shape ofthe cold plate 110 can be effectively maintained. In other words, thecold plate 110 is uneasy to be damaged when the cold plate module 100 orthe main board 300 experiences an impact or a vibration.

Reference is made to FIG. 5 . FIG. 5 is a cross-sectional view along thesectional line B-B of FIG. 1 . In this embodiment, as shown in FIG. 5 ,the first connecting pieces 130 are configured to penetrate through theconnecting portions 123 of the structural piece 120 and connect with themain board 300 to fix the structural piece 120 relative to the mainboard 300.

The first through holes H1 of the connecting portions 123 correspondto the first screw holes S1 of the main board 300. Each of the firstconnecting pieces 130 can be a screw configured to penetrate through thecorresponding first through hole H1 of the connecting portions 123 andcouple with the corresponding first screw hole S1 of the main board 300,so as to fix the position of the structural piece 120 relative to themain board 300 in order to firmly fix the structural piece 120 togetherwith the cold plate 110 on the heat source 200.

In addition, as shown in FIGS. 1-2 and 4-5 , the cold plate module 100further includes a plurality of elastic elements 140. The elasticelements 140 are respectively and elastically connected between thecorresponding connecting portion 123 and the corresponding firstconnecting piece 130. In this way, when the structural piece 120 isfixed on the main board 300 by the first connecting pieces 130, theelastic elements 140 will be compressed, and the force that the coldplate 110 exerting on the heat source 200 from the structural piece 120can be cushioned. Thus, the structural piece 120 is avoided from beingcrushed by the heat source 200 or the cold plate 110. In practicalapplications, each of the elastic elements 140 can be a spring. However,this does not intend to limit the present disclosure.

Moreover, as shown in FIGS. 1-2 , the cold plate module 100 furtherincludes a plurality of second connecting pieces 150. The secondconnecting pieces 150 are configured to penetrate through the plate body122 of the structural piece 120 and connect with the cold plate 110 tofix the plate body 122 relative to the cold plate 110. This means thestructural piece 120 is fixed on the cold plate 110, such that the thirdsurface 121 of the structural piece 120 and the second surface 112 ofthe cold plate 110 abut against each other.

To be more specific, as shown in FIG. 2 , the cold plate 110 has aplurality of second screw holes S2. As shown in FIGS. 2-3 , the platebody 122 of the structural piece 120 has a plurality of second throughholes H2. The second through holes H2 of the plate body 122 correspondto the second screw holes S2 of the cold plate 110. Each of the secondconnecting pieces 150 can be a screw configured to penetrate through thecorresponding second through hole H2 of the plate body 122 and couplewith the corresponding second screw hole S2 of the cold plate 110, so asto fix the structural piece 120 on the cold plate

Furthermore, as shown in FIGS. 1-4 , the plate body 122 of thestructural piece 120 has a plurality of third through holes H3. The coldplate 110 includes a main body 113, an inlet port 114 and an outlet port115. The first surface 111 and the second surface 112 are located on themain body 113. The inlet port 114 and the outlet port 115 arerespectively connected with the second surface 112 and respectivelypenetrate through the corresponding third through hole H3 of the platebody 122. The inlet port 114 is configured to allow a cooling liquid(not shown) to flow into the main body 113. The outlet port 115 isconfigured to allow the cooling liquid to flow out from the main body113. The cold plate module 100 further includes a first connecting port160 and a second connecting port 170. The first connecting port 160 isconnected with the inlet port 114 and is configured to connect to acooling liquid supplying source (not shown). The second connecting port170 is connected with the outlet port 115 and is configured to connectto a cooling liquid collector (not shown).

During the operation of the cold plate module 100, the cooling liquidsupplying source supplies the cooling liquid. The cooling liquidsequentially flows through the first connecting port 160 and the inletport 114 and enters into the main body 113 of the cold plate 110. Sincethe first surface 111 located on the main body 113 abuts against theheat source 200, the heat energy of the heat source 200 can betransferred to the cooling liquid inside the main body 113, such thatthe cooling liquid is heated up. The heated cooling liquid thensequentially flows through the outlet port 115 and the second connectingport 170 and flows to the cooling liquid collector. For example, theheated cooling liquid collected by the cooling liquid collector isflowed back to the cooling liquid supplying source after treatment ofcooling down.

On the other hand, moreover, as shown in FIGS. 2-4 , the plate body 122of the structural piece 120 has a plurality of inner edges 126. Theinner edges 126 define the third through holes H3. As shown in FIG. 4 ,an outer edge 116 of the inlet port 114 and an outer edge 117 of theoutlet port 115 of the cold plate 110 are respectively and at leastpartially connected with the corresponding inner edge 126. In this way,as the inlet port 114 and the outlet port 115 of the cold plate 110 abutagainst the inner edges 126 of the plate body 122, the relative positionof the structural piece 120 and the cold plate 110 can be furthersecured.

In conclusion, the aforementioned embodiments of the present disclosurehave at least the following advantages:

(1) As the bending portions are connected between the plate body and theconnecting portions, the fourth surfaces of the connecting portions andthe third surface of the structural piece have a height difference. Inother words, the fourth surfaces of the connecting portions and thethird surface of the structural piece are not located on the same heightlevel. In this way, the structural piece has a reinforced moment ofinertia. This means the structural piece has a good structural strengthand is uneasy to be deformed.

(2) Since the structural piece has a good structural strength, when thecold plate module or the main board experiences an impact or avibration, the structural piece is uneasy to be deformed and thestructural piece can maintain its original shape. In this way, thanks tothe structural strength of the structural piece, the cold plate abuttingagainst the third surface of the structural piece will not be deformedunder an impact or a vibration. Thus, the shape of the cold plate can beeffectively maintained. In other words, the cold plate is uneasy to bedamaged when the cold plate module or the main board experiences animpact or a vibration.
